Germanium Oxide
Cas No.: 1310-53-8
Formula: GeO2
Germanium is a rare metal and an important semiconductor material. It is insoluble in water. Its chemical properties are stable. It does not interact with air or water vapor at room temperature. However, germanium dioxide is quickly formed at 600-700 C.
Grade: High purity grade.
Uses:
1. It is used in germanium production and electronic industry. Used as semiconductor material. It is prepared by thermal oxidation of germanium or hydrolysis of germanium tetrachloride.
2. Used as raw materials for the preparation of metal germanium and other germanium compounds, as catalysts for the preparation of polyethylene terephthalate resin, as well as spectral analysis and semiconductor materials.
3. Optical glass phosphor can be manufactured. It can be used as catalyst for conversion, dehydrogenation, adjustment of gasoline fraction, production of color film and polyester fiber in petroleum refining. Moreover, germanium dioxide is also a catalyst for polymerization. Glass containing germanium dioxide has high refractive index and dispersion properties. It can be used as wide-angle camera and microscope lens. With the development of technology, germanium dioxide is widely used to produce high-purity germanium, germanium compounds, chemical catalysts and pharmaceutical industry, PET resin, electronic devices, etc.
Packing: 1KG/polyethylene bag or as per customers’ requirements.
